Surface Forms

phylum Chaetognatha singular
phyla Chaetognatha plural

Morphology

phylum + Chaetognatha

The phrase is a straightforward compositional label: 'phylum' (a taxonomic rank) combined with the taxon name 'Chaetognatha' yields the meaning 'the phylum that contains Chaetognatha (arrowworms)'. Taxonomic naming is a regular, cross-linguistic pattern, so a B1 learner who knows both constituent words would readily infer the MWE's meaning.

Etymology

Phylum Chaetognatha comes from Greek parts chaeto meaning 'bristle' and gnatha meaning 'jaw'. The name describes the tiny arrowworms' bristle-like jaws they use to catch food in the ocean, so it helps you remember this group of small marine worms.
